Cefpodoxime proxetil (CPDX-PR, CS-807) was given orally to 18 children with acute bacterial infections including 10 with acute tonsillitis, 3 with acute bronchitis, 1 with pneumonia, 3 with staphylococcal scalded skin syndrome and 1 with infectious impetigo. Daily dosages per kg bodyweight ranging from 7.5 to 18 mg were given in 2 or 3 divided doses per day for 5 to 15 days. Clinical responses were excellent in 3 (16.7%), good in 11 (61.1%), fair in 4 (22.2%) and poor in 0 (0%), with an overall efficacy rate of 77.8%. Good bacteriological responses were obtained in 6 out of the 7 cases from which pathogens were identified. No side effect was observed. The above results suggest that CPDX-PR is a useful new oral cephalosporin derivative for the treatment of bacterial infections in children.

Ceftriaxone-related haemolysis resulted in the death of one of our patients (patient 2), and caused acute renal failure in the other (patient 1). The DATwas strongly positive for anti-C3d and anti-IgG in one case (patient 2), and for anti-C3d alone in the other (patient 1). The serum of patient 1 reacted with red blood cells only in the presence of ex vivo antigens, while that of patient 2 reacted positively to native ceftriaxone and its ex vivo antigen. In the latter patient, the antibodies appeared to cross-react with native cefotaxime whereas, in the first patient, they weakly cross-reacted only with the ex vivo antigens of cefotaxime and cefpodoxime proxetil.

The antimicrobial activity of cefpodoxime, the active metabolite of the new cephalosporin ester cefpodoxime proxetil, in comparison to cefixime, cefotiam, cefuroxime, and cefotaxime was determined against a broad spectrum of freshly isolated gram-positive and gram-negative bacterial strains. Cefpodoxime was demonstrated to be inhibitory at concentrations of less than or equal to 1 mg/l against 90% of strains of Moraxella catarrhalis, Haemophilus influenzae, Escherichia coli (beta-lactamase- negative strains), Klebsiella spp., Serratia spp., Proteus mirabilis, Proteus vulgaris, Providencia spp., and Salmonella spp. This antimicrobial activity of cefpodoxime was generally superior to that of cefuroxime and similar to that of cefixime. Cefpodoxime was active at less than or equal to 1 mg/l against 50% of the members of beta-lactamase-producing Escherichia coli, Enterobacter cloacae, Enterobacter aerogenes, Citrobacter spp., and Morganella morganii. Cefpodoxime proved to be highly inhibitory against group A, B, and G streptococci and Streptococcus pneumoniae (MIC90 less than 0.015 mg/l). The MICs of cefpodoxime and those of the other cephalosporins were less than 2 mg/l for greater than or equal to 90% of the strains of Staphylococcus aureus and Staphylococcus epidermidis, with the exception of cefixime which had no activity with MICs below 8 mg/l against these bacteria. Pseudomonas spp., Acinetobacter spp., and Enterococcus spp. were resistant to cefpodoxime. The antibacterial activity of cefpodoxime was only to a minor degree influenced by different growth conditions with the exception of high inoculum sizes against some beta-lactamase producing strains of gram-negative bacilli.(ABSTRACT TRUNCATED AT 250 WORDS)

vantin reviews

Multiple dose pharmacokinetics of a new third-generation cephalosporin, cefpodoxime, were evaluated in adults (15, 18-60 years) and elderly adults (10, greater than or equal to 70 years), all out-patients suffering from acute lower respiratory tract infection. A dose of 200 mg cefpodoxime proxetil (expressed in mg cefpodoxime) was administered 12-hourly for seven to ten days and timed blood samples were evaluated on days 0, 3, 5, 6/7 and on the last day of treatment. Results showed that the pharmacokinetics in adult and elderly patients were comparable with those of healthy volunteers and with each other, with the exception of one elderly patient with severe renal impairment. Dosage adjustment of cefpodoxime proxetil does not therefore appear to be necessary in the elderly unless there is evidence of severe renal insufficiency.

In US, pneumococcal conjugate vaccine (PCV7) had reduced the burden of AOM and changed the profile of the disease. Prior to PCV7 implementation in France, AOM represented 8% of pediatricians visits and failure rate was 12%. The aim of this study is to describe the epidemiologic characteristics of AOM after PCV7 implementation.

Cefpodoxime is a semi-synthetic, third generation cephalosporin. The drug is available for use as a prodrug-Cefpodoxime proxetil, which is absorbed readily from the gut. It reaches adequate levels exceeding the MIC in most of the body fluids. It is excreted by kidneys, unchanged. Dose needs adjustment in compromised renal function. The drug is active against common gram-positive cocci like staphylococci including penicillinase producing strains, streptococci and gram negative bacteria like Hemophilus, E. coli, Klebsiella, Moraxella, Meningococci, Gonococci etc. The drug is useful in common upper and lower respiratory tract infections, sinusitis, and otitis media. The drug is also used in skin and soft tissue infections, urinary tract infection and respiratory tract infection. Cefpodoxime is being used as a step down from parenteral cephalosporin. The recommended dose is 8-10 mg/kg/d in a single or two doses. Different schedules have been given for different infections. The drug is safe, effective as a short course (5 vs. 10 days). With a low incidence of side effects, and twice a day dosing, it proves to be a useful drug.

The risk for a child to carry penicillin-resistant S. pneumoniae (MIC > or = 0.125 mg/l) did not increase after antibiotic treatment: 84 of 364 (23.1%) before, 70 of 364 (19.2%) after. There was a significant decrease of penicillin-susceptible S. pneumoniae carriage, 117 of 364 (32.1%) before treatment compared with 24 of 364 (6.6%) (P = 0.0001) after treatment. However, among the children carrying S. pneumoniae at the end of the treatment there was an increase in the percentage of penicillin-resistant pneumococci: 84 of 201 (41.8%) before treatment and 70 of 94 (74.5%) after treatment. Among the 94 children carrying S. pneumoniae at the end of the treatment, 22 did not harbor pneumococcus before, 16 carried another genotypically different serotype and 56 harbored the same serotype. Among these 56 children 2 patients harbored strains that had increased MICs for the tested beta-lactam antibiotics. The randomly amplified polymorphic DNA analysis showed that in one case, the strains were genetically different.

vantin renal dosing

The disposition of cefpodoxime in 24 subjects with various degrees of renal function after administration of a single oral dose of 200 mg of cefpodoxime proxetil (equivalent to 200 mg of cefpodoxime activity) was studied. Subjects were assigned to one of four groups (six per group): group I, normal renal function (creatinine clearance [CLCR], greater than ml/min); group II, mild renal impairment (CLCR, 50 to 80 ml/min); group III, moderate renal impairment (CLCR, 30 to 49 ml/min); or group IV, severe renal impairment (CLCR, 5 to 29 ml/min). Although cefpodoxime terminal elimination half-life in group I (2.55 +/- 0.25 h [mean +/- standard deviation]) was not significantly different from that in group II (3.53 +/- 0.74 h), the half-life values for group III (5.90 +/- 1.67 h) and group IV (9.80 +/- 1.21 h) were significantly prolonged compared with those of group I. The mean absorption rate constant was similar among groups and ranged from 0.68 to 0.85 h-1. All groups exhibited absorption lag-times which were comparable (0.30 to 0.41 h), and the apparent volume of distribution was similar among groups. Cefpodoxime apparent total body clearance (CLP/F) values in groups II, III, and IV (132 +/- 29, 112 +/- 41, and 55.7 +/- 9.9 ml/min, respectively) were significantly lower than that in group I (238 +/- 44 ml/min). Cefpodoxime CLP/F was positively correlated with CLCR (r2 = 0.79; P less than 0.05): CLP/F = (1.9 CLCR) + 18.4. Renal clearance also declined with decreasing renal function. Adjustments in cefpodoxime organism and on the site and severity of infection. Simulated plasma concentration-time data from this study suggest that 200 mg of cefpodoxime proxetil administered every 12 to 24 h to subjects with CLcr between 30 and 49 ml/min and 200-mg dose taken every 24 h by subjects with CLcr between 5 and 29 ml/min will maintain cefpodoxime concentration in plasma similar to those in subjects with normal renal function who receive a standard dosage mg every 12 h.

It was found that 62.68% were males, 26% patients were in the age group 26-35 years, followed by 22.8% belonging to the age group 26-35 years. Maximum number of patients were diagnosed with ear (37.3%) and throat (36.2%) infections. The most frequently prescribed antibacterials were β-lactams (45.52%) followed by quinolones (26.31%). The most commonly used agent in penicillins was amoxicillin and clavulanic acid (21.74%), in cepahalosporins was cefpodoxime proxetil (5.49%) and in quinolones was gemifloxacin (14.41%). Further, 66.67% of the patients received single antibacterial drug and the average number of antibacterial agents prescribed per patient per course was found to be 1.58. It was also observed that 70.71% of the antibacterials were prescribed by oral route. The most concomitant conditions were found to be diabetes (10.5%), hypertension (6.16%) and coronary heart disease (5.07%). All the drugs were prescribed by their brand names and 48.91% patients showed good adherence with the prescribed therapy.

Between October, 1996, and April, 1997, 450 children (mean age, 14.3 months) were enrolled, 227 in the 5-day group and 223 in the 10-day group. In the per protocol analysis clinical success was obtained on Days 12 to 14 after the beginning of treatment (main analysis) in 175 (84.1%) of the 208 children receiving the 5-day regimen and 194 (92.4%) of the 210 children receiving the 10-day regimen (P = 0.009). The superiority of the standard regimen was more marked among children cared for outside their homes (92.5% vs. 81.5%). Clinical success persisted on Days 28 to 42 among 134 (85.4%) of the 157 assessable patients in the 5-day group and 144 (83.7%) of the 172 assessable patients in the 10-day group (P = 0.68).

Twelve patients with respiratory tract infections were treated with cefpodoxime proxetil (CS-807, CPDX-PR), a new cephem antibiotic. It was given orally at a dose of 200 mg 2 times a day for 4 approximately 15 days. Its clinical effects were evaluated as excellent in 1 case, good in 9 cases and poor in 2 cases. The efficacy rate was 83.3%. Its bacteriological effects were evaluated as eradication in 5 strains and decrement in 1 strain. The eradication rate was 83.3%. No adverse reactions and disorder of laboratory findings due to CPDX-PR were observed.

vantin dosing

Learning about the behavior of a drug in biological environment enables application of better formulation strategies to improve bioavailability of the same. Cefpodoxime proxetil (CP) is a prodrug, which is orally administered cephalosporin with only 50% absolute bioavailability. Despite previous studies, reasons responsible for low bioavailability of CP remain poorly understood. The present study tries to ascertain reasons for the low oral bioavailability of CP. The in vitro, in situ and ex vivo studies showed interesting results, where metabolism of CP into cefpodoxime acid (CA) inside the intestinal epithelial cell and preferential efflux of CA into lumen was identified as primary reason for low oral bioavailability of CP. Presence of specific carriers or transportation mechanism on the apical side membrane of enterocyte, than basal side of the same was observed.

Cefpodoxime, the deesterified part of the orally available cefpodoxime proxetil, is active against most Enterobacteriaceae with MIC50 of 0.06 to 2 mg/l. Only Enterobacter cloacae and Citrobacter freundii strains show MIC50 of 4 mg/l. Coagulase negative staphylococci have a MIC50 of 2, while Staphylococcus aureus strains have a MIC of 4 mg/l. In comparison to other orally available cephalosporins cefpodoxime is slightly less active than cefixime and cefotiam against gram-negative bacteria but more active than cefuroxime, cefaclor, and cephalexin. Against staphylococci the activity of cefpodoxime is comparable to that of cefotiam and cefuroxime and superior to cefaclor and cephalexin, while cefixime does not have sufficient activity against these species. Like all cephalosporins cefpodoxime has no activity against enterococci.

Acute bacterial rhinosinusitis (ABRS) is a common reason for healthcare visits, and one of the more common reasons for the use of antibiotics. In an effort to improve the diagnosis and appropriate therapy of ABRS, several guidelines have been developed. Current guidelines recommend extended-spectrum cephalosporins as one of the first-line options for the treatment of this condition. In addition, most cephalosporins recommended by recent guidelines (e.g. cefuroxime axetil Buy Cenforce 100 , cefpodoxime proxetil and cefdinir) are unlikely to be associated with cross-reactivity with penicillins, and may be considered effective alternatives to amoxicillin in adults who are allergic to penicillin.

AOM is one of the most common pediatric infections requiring a prescription for an antimicrobial agent. The optimal approach to treatment of AOM requires early, efficacious, and practical therapy. Several experts and organizations have developed recommendations for the management of AOM, but the number of these may overwhelm the busy primary care practitioner. A MEDLINE search of the pediatric and Prograf Cost Without Insurance infectious disease literature on AOM treatment recommendations was used to select 3 representative, previously published articles for this review. When selecting an agent, physicians should consider in vitro activity, particularly against drug-resistant Streptococcus pneumoniae; pharmacokinetics; adverse events; palatability of the suspension; and cost. In addition, physicians' clinical experience is an important determinant.

Cefpodoxime proxetil (CFP), a broad-spectrum third-generation cephalosporin, has been used most widely in the treatment of respiratory and urinary tract infections. For bioequivalence study of CFP in rabbit plasma, it was necessary to develop a highly sensitive and selective high-performance liquid chromatographic (HPLC) method with fluorescence (FL) detection. The pre-column labeling of cefpodoxime acid (CFA) (active metabolite) with an efficient benzofurazan type fluorogenic reagent, 4-N,N-dimethyl aminosulfonyl-7-fluoro-2,1,3-benzoxadiazole (DBD-F) was carried out in the present study in 100mM borate buffer (pH=8.5) at 50°C for 15min. The obtained fluorescent products were separated on C18 column with an isocratic elution of the mobile phase, which consists of 10mM phosphate buffer (pH=3.5)/CH3CN (70:30, v/v). The fluorescent product (DBD-CFA) was detected fluorimetrically at 556nm with an excitation wavelength of 430nm. Cefotaxime sodium was used as internal standard. The method was validated according to the requirements of US-FDA guidelines. The correlation coefficient of 0.999 was obtained in the concentration ranges of 10-1000ngmL(-1). The limits of detection and quantification (S/N=3) Cenforce 150 Online were 3 and 10ngmL(-1), respectively. Plasma CFA levels were successfully determined in rabbit with satisfactory precision and accuracy. The proposed HPLC-FL method was successfully applied to study bioequivalence in rabbits for two formulations of different brands contained CFP (prodrug) in a randomized, two-way, single-dose, crossover study and all pharmacokinetic parameters for the two formulations were assessed.

We compared the effects of nifedipine and diltiazem on the uptake of cefpodoxime proxetil (CP). The study was aimed at establishing the impact of increased mesenteric blood flow due to calcium channel blockers on passive transport. Twelve volunteers were given CP (200 mg) orally in a crossover design. The absorption, disposition, and elimination parameters of cefpodoxime were compared among the following three treatment groups: CP alone Is Cialis A Prescription Drug , CP following oral administration of diltiazem (60 mg), or CP following oral administration of nifedipine (20 mg). No statistically significant difference in pharmacokinetic parameters was observed between the three treatment groups.

The efficacy of CS-834, a novel oral carbapenem, was assessed by using a murine model of pneumonia caused by penicillin-susceptible and penicillin-resistant Streptococcus pneumoniae and was compared with those of oral cephems, i.e., cefteram pivoxil, cefpodoxime proxetil, cefdinir, and cefditoren pivoxil. Intranasal inoculation of 10(6) CFU of penicillin-susceptible or penicillin-resistant S. pneumoniae in the exponential growth phase induced pneumonia and bacteremia in ddY mice within 48 h. For the Rulide Roxithromycin Dosage treatment of infections caused by the penicillin-susceptible strain the antibiotics were administered orally at 0.4, 2, and 10 mg/kg of body weight twice daily for 2 days beginning at 24 h after bacterial inoculation, and for the treatment of infections caused by a penicillin-resistant strain the antibiotics were administered at 2, 10, and 50 mg/kg twice daily for 2 days beginning at 24 h after bacterial inoculation. Among the antibiotics tested, CS-834 exhibited the most potent efficacy against both types of strains. Against infections caused by penicillin-susceptible S. pneumoniae, CS-834 at all doses significantly reduced the numbers of viable cells in both the lungs and blood. Cefpodoxime proxetil at all doses and cefteram pivoxil and cefditoren pivoxil at doses of 2 and 10 mg/kg showed comparable efficacies. Against infections caused by penicillin-resistant S. pneumoniae, CS-834 at doses of 10 and 50 mg/kg showed the most potent efficacy among the antibiotics tested, resulting in the maximum decrease in the numbers of viable cells in the lungs. Comparable efficacies were observed with cefteram pivoxil and cefpodoxime proxetil at doses of 50 mg/kg each. The concentration of CS-834 in the lungs and blood was higher than that of cefdinir and was lower than those of the other antibiotics tested, suggesting that the potent therapeutic efficacy of CS-834 reflects its strong activity against S. pneumoniae.

Most authorities continue to recommend penicillin as the treatment of choice for group A streptococcal pharyngitis. If penicillin is used, 10 days of treatment are necessary to achieve a clinical and bacteriologic cure. The usually recommended penicillin V dose is 250 mg (400,000 IU) three times daily. Twice daily dosing is acceptable to some authorities if compliance is good. However, oral penicillin fails to eradicate group A streptococci from the pharynx in up to 17% of cases; in some studies 30% failure rates have been reported. Several European and United States studies indicate that a variety of oral cephalosporins, when used for 10 days, are significantly superior to penicillin V in eradicating group A streptococci from the pharynx. For example cefpodoxime proxetil given twice daily for 10 days is comparable to penicillin V given three times daily for 10 days in achieving a clinical cure and appears to be significantly superior to penicillin in eradicating group A streptococci from the pharynx. Preliminary studies from Europe and the United States strongly suggest that 5-day therapy with cefpodoxime (or other selected oral cephalosporins) is at least as effective, clinically Baidyanath Triphala Guggulu Tablets Benefits and microbiologically, as 10-day therapy with penicillin V. Further clinical trials are warranted to confirm the adequacy of 5-day treatment and to assess the efficacy of cefpodoxime and other agents in preventing rheumatic fever.

Chromatographic separation of CFA and internal standard (IS) was achieved by a RP18(C18), Phenomenax®100, (250×4.6mm) with the mobile phase consisting of (0.02mol/l (20mM) ammonium acetate solution and acetonitrile (92:8, v/v, pH=4.6) at a flow rate of 1.0ml/min. The method was validated according to the requirements of US-FDA guidelines for bioanalytical method validation. The linear regression analysis for the calibration plots showed good linear relationship (R(2)=0.9905) in the working concentration range of 0.5-50μg/ml. The limits of detection and quantification (S/N=3) were 0.069 and 0.136μg/ml. Plasma CFA levels were successfully determined in rabbit with satisfactory precision and accuracy. The analyte was found to be stable after a number of stability studies. The proposed HPLC method was successfully applied to pharmacokinetic study in rabbits for CFP loaded CH-ALG beads and marketed immediate release (IR) tablets. All pharmacokinetic parameters were assessed.

OBJECTIVE: To investigate changes in fecal flora and multiple-dose pharmacokinetics with the oral antibiotics ceftibuten 400 mg daily and cefpodoxime proxetil (CPX) 200 mg every 12 h, compared to amoxycillin/clavulanate 500/125 mg every 8 h during and following 1 week of medication. METHODS: In an open randomized triple crossover design, 18 (nine female, nine male) healthy volunteers received each drug for 7 days, followed by a 'washout' period of 4 weeks. Serum and urine levels of the substances were determined by bioassay, and for ceftibuten isomers by high-pressure liquid chromatography. Statistical analysis of quantitative aerobic and anaerobic cultures of feces was performed, and beta-lactamase activity was determined. RESULTS: Ceftibuten showed a mean Cmax of 18.9 (SD 3.0) mg/L, a terminal half-life of 2.89 h, and an AUCtot of 100 (21.8) mg.h/L; protein binding was 63.7 (5.1)%, and accumulation was marginal. Cefpodoxime proxetil had a Cmax of 1.92 (0.61) mg/L, a terminal half-life of 1.97 (0.42) h and an AUCtot of 10.8 (3.3) mg.h/L; no accumulation was seen. Amoxycillin and clavulanate had Cmax values of 7.15 (2.16) mg/L and 3.39 (1.31) mg/L, terminal half-life values of 1.03 (0.15) h and 0.93 (0.17) h, AUCtot values of 20.0 (4.2) mg.h/L and 8.87 (3.10) mg.h/L, and there was no accumulation. Statistical analysis for ech microorganism in fecal samples showed significant differences between amoxycillin/clavulanate and the two third-generation cephalosporins, but virtually no differences between ceftibuten and Coumadin Levels Medication cefpodoxime proxetil. Eleven of 12 volunteers reported loose stools (days 2-7, mean duration 4.4 (SD 2.7) days) with amoxycillin/clavulanate, but nobody during ceftibuten administration and one volunteer during cefpodoxime proxetil administration. CONCLUSIONS: Ceftibuten showed excellent and cefpodoxime favorable pharmacokinetic properties, with significantly less pronounced fecal flora changes and intestinal side effects compared to amoxycillin/clavulanate. The multiple crossover design allows powerful microbiological statistical analysis and pharmacokinetic parameter comparisons.

A sensitive and selective electrochemical method for Cefpodoxime Proxetil (CP) determination has been developed by incorporating gold nanoparticles (AuNPs) onto the poly-1,5-diaminonapthalene layer (p-DAN) coated pyrolytic graphite. The modified sensor was characterized by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The sensor exhibited an effective catalytic response towards oxidation of CP with excellent reproducibility and stability. The peak current of CP was found to be linear in the range of 0.1-12 μM and detection limit and sensitivity of 39 nM (S/N=3) and 4.621 μA μM(-1), respectively, were observed. The method was successfully applied for the determination of CP in pharmaceutical formulations and human urine samples. The common metabolites present in human urine such as uric acid, ascorbic acid, Viagra 8 Tablet xanthine and hypoxanthine did not interfere in the determination. A comparison of the results obtained by using developed method with high performance liquid chromatography (HPLC) indicated a good agreement. The method is simple, sensitive, rapid and precise and is useful for the routine determination of CP in pharmaceutical dosages and biological samples.
